Notes. Number of optical GRBs with a plateau and redshift needed to reach the precision of ΩM as obtained in studies by Conley et al. (2011); Betoule et al. (2014); Scolnic et al. (2018) (for SNe Ia). This is an extension of the table provided in Dainotti et al. (2022a). The term n=1 indicates that the error bars on the GRB plateau parameters are full width, while n=2 indicates that the error bars are halved. The “LCR” indicates that the estimates for the number of GRBs have been boosted by using LCR, while “ML” indicates that the estimates have been boosted by using ML.
